<p>
      In order to hide the internals of the file manager from the extensions, the <code class="systemitem">thunarx</code> library provides an abstraction layer, which includes
      interfaces accessible to the extension, that are implemented by the file manager at runtime.
    </p>
<p>

    </p>
<p>
      Currently the abstraction layer consists of the interface <a class="link" href="ThunarxFileInfo.html" title="ThunarxFileInfo"><span class="type">ThunarxFileInfo</span></a>, which provides
      extensions with a way to access information about a file handled within
      the file manager, the class <a class="link" href="ThunarxPropertyPage.html" title="ThunarxPropertyPage"><span class="type">ThunarxPropertyPage</span></a>, which
      is the base class for widgets that can be added to the properties dialog by
      extensions, the interface <a class="link" href="ThunarxProviderPlugin.html" title="ThunarxProviderPlugin"><span class="type">ThunarxProviderPlugin</span></a>, which
      hides the details of dynamic type registration from the extensions, and the
      class <a class="link" href="ThunarxRenamer.html" title="ThunarxRenamer"><span class="type">ThunarxRenamer</span></a>, which
      is the abstract base class for renamers that can be used in the bulk rename
      dialog provided by Thunar to rename multiple files at once.
